SOLE-CEMENTING MACHINE.

Application filed March 9, 1927. Serial No. 174,035.

upon a cementitious covering as applied upon a ground surface of the shoe proper. The ease of application, the 'sureness of proper arrangement and the accuracy of details incident to the completed article will be fully described during the following description of the drawings and further pointed out in the claim.

In the drawings, Fig. 1 represents a side elevation of the shoe, as installed upon my machine, and showing the means for holdingand maintaining the arranged position of the sole thereon and. during the interval necessary for performing the work. Fig. 2 representsm cross-sectional view taken along the line 11-11 in Fig. 1 and looking in the direction of the arrows. Similar numerals of reference indicate corresponding parts throughout.

Referring to the drawings; upon a suit able base 10, which may be of wood, metal or other substance and of such shape as will position it most advantageously for the opera tor, is installed a standard for a shoemakers last. In its preferred form I employ a jack, such for instance, as that shown at 11, having a handle 12 pivoted at 13 to raise the customary element 15 upon which a last, such as 16, is fitted as the head element of the jack. A trip 14, as usual to jacks of this character, is illustrated. The shoe 17 is placed upon the last 16, it being understood that right or left lasts of desired sizes are used, as necessary. The bottom of the shoe is first prepared and then a cementitious coating is applied thereto as at 18*. A sole 19, of suitable material, is then placed upon the base 18 previously prepared. The shoemaker, customarily, then arranges this sole to a proper position and then drives in a nail at the point 20 to temporarily position the sole in place.

The intent now is to provide the most practical as well as effective way to cause this sole to adhere in a proper manner to the base 18, both for appearance as well as durability and workmanship in general. Suitable anchor supports, such for instance as the eye bolts 21 and 22, on the base 10, are ar ranged below and upon either side of the supported shoe 17 and forward of the jack. At 23-23 are seen a pair of links suitably attached to the supports 21 and 22, the opposite ends of the flexible belting 24 are attached thereto and are preferably bent back and stitched as at 25. lNhile not restricting myself to any particular form or article illustrated, I suggest the use of old automobile tubing as a. sheap and satisfactory mat rial for the flexible belting. This can be turned wrong side out which gives a roughened face effect and may be dyed for appearance of desired. I now place this belt, as at 2%, over the attached sole and forward of the nail 20 or so that it reaches to or over the front end ofthe shoe at the toe. Next a narrower belting 26 of like material similarly attached at its ends to links 27 carried by anchor bolts 28 forwardly positioned beyond the bolts 21, is looped over the rear edge portion of the sole behind the nail 20. The handle 12 of the jack is now actuated to raise the member 15, thereby creating considerable tension on the belting elements 24 and 26. During this jacking operation, the work is entirely under the eyes of the shoemaker, so that he can'properly manipulate and arrange or force the sole to assume such position and shape with reference to the edges of the base 18 of the shoe, as, in his estimation, will give the required result upon the later release of the jack pressure by tripping the latch 14, as will be readily understood. After the sole has properly stuck, such pressure is removed and the sole dressed and smoothed up.

Various modifications of the shape of the last may be employed such as will more fully harmonize with the lines and positions of the pressure applications. Such other modifications may. be employed as lie within the scope of the appended claim.

Having fully described my invention what I now claim as new and desire to secure by Letters Patent is:

In a sole cementing machine, a base element, a shoe last adj ustably positionable from said base; belting detachably connected to the base and for looping over a shoe when carried by the last: and a jack intermediate the last and base for actuating said last to stretch said belting.

In testimony whereof, Ihereunto aflix my
